Nowitzki recorded his 10,000th career rebound during Tuesday's game against the San Antonio Spurs, joining a Hall of Fame-worthy list in the process. He became the seventh player in NBA history with 27,000 career points and 10,000 rebounds; Kareem Abdul-Jabbar, Karl Malone, Wilt Chamberlain, Shaquille O'Neal, Moses Malone and Elvin Hayes are the others.

"That's pretty unbelievable," Nowitzki said. "I came in as probably the worst 7-foot rebounder in the league at the time."

That changed over the years, as Nowitzki went from averaging 3.4 rebounds his rookie season to 6.5 in his sophomore, before skyrocketing in the following seven seasons. He averaged 9.3 rebounds per game from 2000-01 to 2006-07.

Even more impressive is how well-rounded Nowitzki's game has been since breaking into the league during the 1998-99 season.
